  The minimum spacing of the national standard pp fitting is 100mm. However, the maximum distance should not exceed 300mm. The distance is too small, the coil is difficult and the construction is not smooth, and the distance is too large to meet the heat dissipation requirements.

  
  Generally 25cm pitch for household use, 20cn is also acceptable. Generally 25-30cm spacing in public places. The spacing of floor heating pipes is designed to range from 100MM to 300M according to different heating conditions and room patterns. Generally, the pipe spacing is about 200MM.

  
  What is the spacing of the floor heating pipes? The standard should be 20-30; 25 on the sunny side and 20 on the negative side.

  
  Fix the heating pipe (PEX-A pipe) with plastic pipe clamps to the benzene board according to the required spacing of the floor heating design. The distance between the fixed points, the distance between the elbows is not more than 300mm, and the distance between straight sections is not more than 600mm and more than 90° Both ends and midpoints of the curved pipe section should be fixed. The bending radius of the pipe should not be less than 8 times the outer diameter of the pipe. During the installation process, the pipeline should be prevented from being contaminated, and the pipe openings should be blocked in time after the heating pipes of each loop are laid.

  
  The distance between 20-30 cm is in line with the requirements, and the distance between our construction floor heating pipes is 20 cm.

  
  The 16 pipe usually means that the inner wall of the floor heating pipe is 16mm and the outer wall of the floor heating pipe is 20mm. The 20 floor heating pipe means that the inner wall of the pipe is 20mm and the outer wall of the floor heating pipe is 25mm.

  
  There are two types of floor heating pipes, one is 20mm pipe diameter, the other is 16mm pipe diameter. The pipe spacing is different, and the craftsmanship is different in all aspects. According to the "Ground Radiant Heating Installation Specification", which is what we usually call the national standard , The pipe spacing of the toilet is in the range of 150mm~200mm.

  
  Generally, the distance between geothermal pipes should be between 15-25cm. If there are two external walls, the pipes should be encrypted accordingly. The distance between the pipeline and the outer wall should be about 10cm.
  The size of the bedroom and living room is 200mm. This refers to general apartments and townhouses. If the floor heating of a single-family villa is installed, the pipe spacing of the floor heating pipes is generally required to be 150mm, because the single-family villa is not only about 2.8m high like an apartment. The higher the height, the tighter the pipe spacing; if the apartment has a height of 5m or more, or the townhouse has a staggered height, it is better to arrange the density of the pipe spacing at 150mm.

  
  How to calculate the length of the pipeline for floor heating, such as the length of the pipeline with a spacing of 250mm, the room length is 3000, and the width is 45002. The length of the pipeline for floor heating is generally given in the drawing, and there is no need to calculate it. If you want to calculate the length of the pipeline with a spacing of 250mm, Leave 250mm on each side of the room before counting.
  
  
  Blindly narrowing the spacing of Plastic PEX Manifolds will cause the floor heating circuit to increase a lot of turns, increase the thermal resistance, and increase the difficulty of construction, often resulting in poor circulation or local overheating. The reduction of the spacing will seriously affect the performance of the floor heating effect. , It will also add some unnecessary troubles in the future. In order to prevent this kind of phenomenon, the floor heating coil must be calculated and validated in accordance with the normal design and the heat load of the room orientation, the insulation effect of the building, and the required indoor temperature to ensure the comfort of winter heating.

  
  In short, the national standard of the HVAC industry is household heating, and the floor heating pipe spacing between 15cm-20cm is in compliance with the regulations.
